Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
<span>x-y=1 (1)
x+y=3 (2) 
Add (1) and (2) to eliminate y: 
x- y + x - y =1 + 3
2x = 4
x = 4/2

</span><span>x = 2 
Substitute x = 2 into (1) to find y: 
2 + y = 3
y = 3 - 2
y = 1 
The solution is (2, 1) </span>

vodka [1.7K]

Answer:

  • Angle e = Angle <em><u>a</u></em>
  • Angle f = Angle <em><u>c</u></em>
  • Angle a, b and c add upto <em><u>180</u></em><em><u>°</u></em><em><u> </u></em><em><u>,</u></em><em><u> </u></em>as they are on straight line.
  • therefore Angle e , f and b also add upto <em><u>180</u></em><em><u>°</u></em><em><u> </u></em><em><u> </u></em>

Answer:

1. 4(x - 3) = 32

4x - 12 = 32

4x = 44

x = 11

2. 12(2x + 4) = 24

24x + 48 = 24

24x = -24

x = -1

3. 3(3s + 4) = 21

9s + 12 = 21

9s = 9

s = 1

4. 3(c - 2) = 2(c + 3)

3c - 6 = 2c + 6

c - 6 = 6

c = 12

5. 12(r - 3) = 6(r + 3)

12r - 36 = 6r + 18

6r - 36 = 18

6r = 54

r = 9

6. 2(x+5) = 30

2x + 10 = 30

2x = 20

x = 10

7. 3(b+2) = 6(b-2)

3b + 6 = 6b - 12

6 = 3b - 12

18 = 3b

6 = b

8. 4(c-2) = 16

4c - 8 = 16

4c = 24

c = 6

9. 7(y+2) = 28

7y + 14 = 28

7y = 14

y = 2

10. 4(d-2) = 2(d+3)

4d - 8 = 2d + 6

2d - 8 = 6

2d = 14

d = 7

11. 5(L+5) = 35

5L + 25 = 35

5L = 10

L = 2
